Accounting Policies [Abstract]
Significant Accounting Policies	(1) Summary of Significant Accounting Policies (a) Nature of Operations Federated Investors, Inc. and its subsidiaries (collectively, Federated) provide investment advisory, administrative, distribution and other services primarily to Federated mutual funds and Separate Accounts (which include separately managed accounts, institutional accounts, sub-advised funds and other managed products) in both domestic and international markets. For presentation purposes in the Consolidated Financial Statements, the Federated-sponsored mutual funds are considered to be affiliates of Federated. The majority of Federated’s revenue is derived from investment advisory services provided to Federated mutual funds and Separate Accounts through various subsidiaries pursuant to investment advisory contracts. These subsidiaries are registered as investment advisers under the Investment Advisers Act of 1940 and with certain states. Federated mutual funds are distributed by a wholly owned subsidiary, which is a registered broker/dealer under the Securities Exchange Act of 1934 and under applicable state laws. Federated’s investment products are primarily distributed within the wealth management and trust, broker/dealer and global institutional markets. (b) Basis of Presentation The Consolidated Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP). In preparing the financial statements, management is required to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying notes. Actual results may differ from those estimates, and such differences may be material to the Consolidated Financial Statements. (c) Reclassification of Prior Period Financial Statements Certain items previously reported have been reclassified to conform with the current year’s presentation. (d) Principles of Consolidation The Consolidated Financial Statements include the accounts of Federated Investors, Inc. and entities or sponsored products in which Federated holds a controlling financial interest. A controlling financial interest is determined by the extent of Federated’s (1) decision-making ability through voting interests, (2) decision-making ability and rights/obligations to benefits/losses through variable interest or (3) participation in the economic risks and rewards of the entity through variable interests. To the extent Federated’s controlling financial interest in a consolidated subsidiary represents less than 100% of the subsidiary’s equity, Federated recognizes noncontrolling interests in subsidiaries. In the case of consolidated sponsored products (see Note (5)(b)), the noncontrolling interests represent equity which is redeemable or convertible for cash or other assets at the option of the equity holder. As such, these noncontrolling interests are deemed to represent temporary equity and are classified as redeemable noncontrolling interests in subsidiaries in the mezzanine section of the Consolidated Balance Sheets. All other noncontrolling interests in subsidiaries are classified as permanent equity. All significant intercompany accounts and transactions have been eliminated. Beginning on January 1, 2010, Federated adopted the provisions of the Financial Accounting Standards Board’s (FASB) new consolidation model for variable interest entities (VIEs). As a result, Federated applies two different approaches to consider VIEs for possible consolidation. For non-investment fund entities, Federated considers a qualitative model for identifying whether its interest in a VIE is a controlling financial interest. The qualitative model considers whether Federated has: (1) the ability to direct significant activities of the VIE, and (2) the obligation to absorb losses of and/or to provide rights to receive benefits from the VIE that could potentially be significant to the VIE. Federated reevaluates the need for consolidation under this qualitative approach on an ongoing basis. For Federated’s interests in certain investment funds that meet the definition of VIEs, Federated evaluates the extent of Federated’s participation in the economic risks and rewards of the entity based on a quantitative model to determine whether consolidation is necessary. In cases where the results of the quantitative model indicate that Federated’s interest in such an entity absorbs the majority of the variability in the entity’s net assets, Federated is deemed to be the primary beneficiary and thus consolidates the entity. The equity method of accounting is used to account for investments in entities in which Federated’s equity investment gives it the ability to exercise significant influence over the operating and financial policies of the investee. Equity investments are carried at Federated’s share of net assets and are included in either Investments or Other long-term assets on the Consolidated Balance Sheets dependent upon management’s ability and intent to sell the investment. The proportionate share of income or loss is included in Nonoperating income (expenses) – other, net in the Consolidated Statements of Income. (e) Business Combinations Beginning in 2009, business combinations are accounted for under the acquisition method of accounting. Results of operations of an acquired business are included from the date of acquisition. Management estimates the fair value of the acquired assets, including identifiable intangible assets, and assumed liabilities based on their estimated fair values as of the date of acquisition. Any excess fair value of the acquired net assets over the acquisition-date fair value of the consideration transferred, including the fair value of any contingent consideration, is recorded as Goodwill on the Consolidated Balance Sheets. The fair value of contingent consideration is recorded as a liability in Other current liabilities and Other long-term liabilities on the Consolidated Balance Sheets as of the acquisition date. This liability is remeasured at fair value each period end with changes in fair value recognized in Intangible asset related expense on the Consolidated Statements of Income. For a discussion regarding the approach used to estimate the fair value of the liability, see Note (6)(a). (f) Cash and Cash Equivalents Cash and cash equivalents include money market accounts and deposits with banks. (g) Investments Federated's investments are categorized as Investments – affiliates or Investments – other on the Consolidated Balance Sheets. Investments – affiliates represent Federated’s available-for-sale investments in Federated sponsored fluctuating-value mutual funds. These investments are carried at fair value with unrealized gains or losses on securities included in Accumulated other comprehensive loss, net of tax on the Consolidated Balance Sheets. Realized gains and losses on these securities are computed on a specific-identification basis and recognized in Gain on securities, net in the Consolidated Statements of Income. Investments – other represents trading securities held by Federated primarily as a result of consolidating certain Federated-sponsored investment companies. Federated’s trading securities at December 31, 2011 were primarily comprised of high quality short-term debt securities held by a consolidated, non-US dollar-denominated sponsored money market fund, as well as shares of an offshore master fund invested in global project and trade finance transactions and stocks of large-cap U.S. and international companies held by various other consolidated investment companies (see Note (7) for additional information). Trading securities are carried at fair value with changes in fair value recognized in Gain on securities, net in the Consolidated Statements of Income. The fair value of Federated's investments is generally based on quoted market prices in active markets for identical instruments. If quoted market prices are not available, fair value is generally based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, or model-derived valuations in which all significant inputs and significant value drivers are observable in active markets. In the absence of observable market data inputs and/or value drivers, internally generated valuation techniques may be utilized in which one or more significant inputs or significant value drivers are unobservable in the market place. On a periodic basis, management evaluates the carrying value of investments for impairment. With respect to its investments in fluctuating-value mutual funds, management considers various criteria, including the duration and extent of a decline in fair value, the ability and intent of management to retain the investment for a period of time sufficient to allow the value to recover and the financial condition and near-term prospects of the fund and the underlying investments of the fund, to determine whether a decline in fair value is other than temporary. If, after considering these criteria, management believes that a decline is other than temporary, the carrying value of the security is written down to fair value through the Consolidated Statements of Income. (h) Derivatives and Hedging Instruments From time to time, Federated may consolidate an investment product that holds freestanding derivative financial instruments for trading purposes. Federated reports such derivative instruments at fair value and records the changes in fair value in Gain on securities, net on the Consolidated Statements of Income. From time to time, Federated may also enter into and designate as accounting hedges derivative financial instruments to hedge interest-rate exposures with respect to variable-rate loan facilities (cash flow hedges) or to hedge foreign-currency exchange risk with respect to non-US dollar-denominated trading investments in consolidated investment companies (net investment hedges). To qualify for hedge accounting, the derivative must be deemed to be highly effective in offsetting the designated changes in the hedged item. For cash flow hedges and net investment hedges, the effective portions of the change in the fair value of the derivative are reported as a component of Accumulated other comprehensive loss, net of tax on the Consolidated Balance Sheets and subsequently reclassified to earnings in the period or periods during which the hedged item affects earnings. The change in fair value of the ineffective portion of the derivative, if any, is recognized immediately in earnings. If it is determined that the derivative instrument is not highly effective, hedge accounting is discontinued. If hedge accounting is discontinued because it is no longer probable that a forecasted transaction will occur, the derivative will continue to be recorded on the balance sheet at its fair value with changes in fair value included in current earnings, and the gains and losses in Accumulated other comprehensive loss, net of tax will be recognized immediately into earnings. If hedge accounting is discontinued because the hedging instrument is sold, terminated or no longer designated, the amount reported in Accumulated other comprehensive loss, net of tax up to the date of sale, termination or de-designation continues to be reported in Accumulated other comprehensive loss, net of tax until the forecasted transaction or the hedged item affects earnings. See Note (6) and Note (11) for additional information on the fair value of the hedges at December 31, 2011. (i) Property and Equipment Property and equipment are initially recorded at cost and are depreciated using the straight-line method over their estimated useful lives ranging from 1 to 12 years. Leasehold improvements are amortized using the straight-line method over the shorter of their estimated useful lives or their respective lease terms. As property and equipment are taken out of service, the cost and related accumulated depreciation and amortization are removed. The write-off of any material residual net book value is reflected as a loss in Operating expenses – Other in the Consolidated Statements of Income. Management reviews the remaining useful lives and carrying values of property and equipment to determine whether events and circumstances indicate that a change in the useful life or impairment in value may have occurred. Indicators of impairment monitored by management include a decrease in the market price of the asset, an accumulation of costs significantly in excess of the amount originally expected in the acquisition or development of the asset, historical and projected cash flows associated with the asset and an expectation that the asset will be sold or otherwise disposed of significantly before the end of its previously estimated useful life. Should there be an indication of a change in the useful life or an impairment in value, Federated compares the carrying value of the asset to the probability-weighted undiscounted cash flows expected to be generated from the underlying asset over its remaining useful life to determine whether an impairment has occurred. If the carrying value of the asset exceeds the undiscounted cash flows, the asset is written down to fair value which is determined based on prices of similar assets if available or discounted cash flows. Impairment adjustments are recognized in Operating Expenses – Other in the Consolidated Statements of Income. (j) Costs of Computer Software Developed or Obtained for Internal Use Certain internal and external costs incurred in connection with developing or obtaining software for internal use are capitalized. These capitalized costs are included in Property and equipment, net on the Consolidated Balance Sheets and are amortized using the straight-line method over the shorter of the estimated useful life of the software or four years. These assets are subject to the impairment test used for other categories of property and equipment described in Note (1)(i). (k) Intangible Assets Intangible assets, consisting primarily of goodwill, customer relationship intangible assets, renewable investment advisory contracts and noncompete agreements acquired in connection with various acquisitions, are recorded at fair value determined using a discounted cash flow model as of the date of acquisition. The discounted cash flow model considers various factors to project future cash flows expected to be generated from the asset. Given the investment advisory nature of Federated’s business and of the businesses acquired over the years, these factors typically include: (1) an estimated rate of change for underlying managed assets; (2) expected revenue per managed asset; (3) incremental operating expenses; (4) useful life of the acquired asset; and (5) a discount rate. Management estimates a rate of change for underlying managed assets based on a combination of an estimated rate of market appreciation or depreciation and an estimated net redemption or sales rate. Expected revenue per managed asset, incremental operating expenses and the useful life of the acquired asset are generally based on contract terms, average market participant data and historical experience. The discount rate is estimated at the current market rate of return. After the fair value of all separately identifiable assets has been estimated, goodwill is recorded to the extent the consideration paid for the acquisition exceeds the sum of the fair values of the separately identifiable acquired assets and assumed liabilities. Federated amortizes finite-lived identifiable intangible assets using a method that reflects the pattern in which the economic benefits of the intangible asset are expected to be consumed or otherwise used. Federated uses either the straight-line or an accelerated method of amortization after considering specific characteristics of the underlying fund shareholder base to forecast the pattern in which the economic benefits will be consumed, including fund shareholder behavior, demographics and persistency levels. The assets are amortized over their estimated useful lives, which range from 5 to 11 years. Management periodically evaluates the remaining useful lives and carrying values of the intangible assets to determine whether events and circumstances indicate that a change in the useful life or impairment in value may have occurred. Indicators of impairment monitored by management include a decline in the level of managed assets, changes to contractual provisions underlying certain intangible assets and reductions in underlying operating cash flows. Should there be an indication of a change in the useful life or impairment in value of the finite-lived intangible assets, Federated compares the carrying value of the asset and its related useful life to the projected undiscounted cash flows expected to be generated from the underlying asset over its remaining useful life to determine whether impairment has occurred. If the carrying value of the asset exceeds the undiscounted cash flows, the asset is written down to its fair value determined using discounted cash flows. Federated writes-off the cost and accumulated amortization balances for all fully amortized intangible assets. Federated has determined that certain acquired assets, specifically, certain renewable investment advisory contracts, have indefinite useful lives. In reaching this conclusion, management considered the legal, regulatory and contractual provisions of the investment advisory contract that enable the renewal of the contract, the level of cost and effort required in renewing the investment advisory contract, and the effects of obsolescence, demand, competition and other economic factors that could impact the funds’ projected performance and existence. The contracts generally renew annually and the value of these acquired assets assumes renewal. These indefinite-lived intangible assets are reviewed for impairment annually or whenever events or circumstances indicate that a change in the useful life or impairment in value may have occurred. Indicators of impairment monitored by management include a decline in the level of managed assets, changes to contractual provisions of the renewable investment advisory contracts and reductions in underlying operating cash flows. Federated estimates the fair value of the indefinite-lived intangible assets and compares it to the remaining book value of the assets to determine whether an impairment charge is necessary. Impairment is indicated when the carrying value of the intangible assets exceed their fair value. Federated tests goodwill for impairment at least annually or when indicators of potential impairment exist. Goodwill is evaluated at the reporting unit level. Federated has determined that it has a single reporting unit consistent with its single operating segment based on the fact that Federated’s operations are managed as a single business: investment management. Federated does not have multiple operating segments or business components for which discrete financial information is prepared. Federated uses a two-step process to test for and measure impairment which begins with an estimation of the fair value of its reporting unit by considering Federated’s market capitalization. If Federated’s market capitalization falls to a level below its recorded book value of net assets, Federated’s goodwill would be considered for possible impairment. (l) Deferred Sales Commissions Federated pays upfront commissions to broker/dealers to promote the sale of certain mutual fund shares. Under various fund-related contracts, Federated is entitled to distribution and servicing fees from the mutual fund over the life of such shares. Both of these fees are calculated as a percentage of average managed assets associated with the related classes of shares. For certain share classes, Federated is also entitled to receive a contingent deferred sales charge (CDSC), which is collected from certain redeeming shareholders. For share classes that pay both a distribution fee and CDSC, Federated generally capitalizes a portion of the upfront commissions as deferred sales commissions, dependent upon expected recoverability rates. The deferred sales commission asset is amortized over the estimated period of benefit of up to eight years. Deferred sales commission amortization expense was $7.4 million, $12.2 million and $18.5 million for 2011, 2010 and 2009, respectively, and was included in Operating expenses – Other on the Consolidated Statements of Income. Distribution and shareholder service fees are recognized in Other service fees, net-affiliates on the Consolidated Statements of Income over the life of the mutual fund share class. CDSCs collected on these share classes are used to reduce the deferred sales commission asset. Federated reviews the carrying value of deferred sales commission assets on a periodic basis to determine whether a significant long-term decline in the equity or bond markets or other events or circumstances indicate that an impairment in value may have occurred. Should there be an indication of an impairment in value, Federated compares the carrying value of the asset to the probability-weighted undiscounted future cash flows of the underlying asset to determine whether an impairment has occurred. Management writes down the asset balance to fair value when reasonably estimable expected future cash flows are not expected to be sufficient to fully amortize the remaining deferred sales commission asset. For share classes that do not pay both a distribution fee and CDSC, Federated expenses the cost of the upfront commission as incurred in Distribution expense in the Consolidated Statements of Income and credits Distribution expense for any CDSCs collected. (m) Foreign Currency Translation The balance sheets of certain wholly owned foreign subsidiaries of Federated and certain consolidated foreign-denominated investment products are translated at the current exchange rate as of the end of the accounting period and the related income or loss is translated at the average exchange rate in effect during the period. Net exchange gains and losses resulting from these translations are excluded from income and are recorded in Accumulated other comprehensive loss, net of tax on the Consolidated Balance Sheets. Foreign currency transaction gains and losses are reflected in Operating Expenses – Other in the Consolidated Statements of Income. (n) Treasury Stock Federated accounts for acquisitions of treasury stock at cost and reports total treasury stock held as a deduction from Federated Investors shareholders’ equity on the Consolidated Balance Sheets. At the date of subsequent reissue, the treasury stock account is reduced by the cost of such stock on a specific-identification basis. Additional paid-in capital from treasury stock transactions is increased as Federated reissues treasury stock for more than the cost of the shares. If Federated issues treasury stock for less than its cost, Additional paid-in capital from treasury stock transactions is reduced to no less than zero. Once this account is at zero, any further required reductions are recorded to Retained earnings on the Consolidated Balance Sheets. (o) Revenue Recognition Revenue from providing investment advisory, administrative and other services (including distribution, shareholder servicing and retirement plan recordkeeping) is recognized during the period in which the services are performed. Investment advisory, administrative and the majority of other service fees are generally calculated as a percentage of total net assets of the investment portfolios that are managed by Federated. The fair value of the investment portfolios is primarily determined using quoted market prices or independent third-party broker or dealer price quotes. In limited circumstances, a quotation or price evaluation is not readily available from a pricing source. In these cases, pricing is determined by management based on a prescribed valuation process that has been approved by the directors/trustees of the sponsored products. For the periods presented, a de minimus amount of assets under management were priced by Federated management. Federated may waive certain fees for competitive reasons such as to maintain positive or zero net yields, to meet regulatory requirements or to meet contractual requirements. Federated waived fees of $724.9 million, $653.1 million and $645.5 million for the years ended December 31, 2011, 2010 and 2009, respectively, nearly all of which was for competitive reasons. The increase in fee waivers for the year ended December 31, 2011 as compared to the same period of 2010 was primarily due to a $79.1 million increase in fee waivers to maintain positive or zero net yields. Fee waivers may continue to increase in order to maintain positive or zero net yields in addition to other competitive reasons. Fee waivers to maintain positive or zero net yields are partially offset by a related reduction to distribution expense and net income attributable to noncontrolling interests (see Note (4) for additional information on the net impact of these waivers). Federated has contractual arrangements with third parties to provide certain fund-related services. Management considers various factors to determine whether Federated’s revenue should be recorded based on the gross amount payable by the funds or net of payments to third-party service providers. Management’s analysis is based on whether Federated is acting as the principal service provider or as an agent. The primary factors considered include: (1) whether the customer holds Federated or the service provider responsible for the fulfillment and acceptability of the services to be provided; (2) whether Federated has any practical latitude in negotiating the price to pay a third-party provider; (3) whether Federated or the customer selects the ultimate service provider; and (4) whether Federated has credit risk in the arrangement. Generally, the less the customer is directly involved with or participates in making decisions regarding the ultimate third-party service provider, the more supportive the facts are that Federated is acting as the principal in these transactions and should therefore report gross revenues. As a result of considering these factors, investment advisory fees, distribution fees and certain other service fees are recorded gross of payments made to third parties. (p) Share-Based Compensation Federated recognizes compensation costs based on grant-date fair value for all share-based awards granted, modified or settled after January 1, 2006, as well as for any awards that were granted prior to January 1, 2006 for which requisite service has not yet been provided. Federated issues shares for share-based awards from treasury stock. For restricted stock awards, the fair value of the award is calculated as the difference between the closing market value of Federated’s Class B common stock on the date of grant and the purchase price paid by the employee, if any. Federated estimates the grant-date fair value of stock options using the Black-Scholes option-pricing model. Federated’s awards are generally subject to graded vesting schedules. Compensation expense is adjusted for estimated forfeitures and is recognized on a straight-line or modified straight-line basis over the requisite service period of the award. Compensation expense also includes dividends paid on forfeited awards. Forfeiture assumptions are evaluated on a quarterly basis and updated as necessary. For awards granted prior to January 1, 2006 with provisions that allow for accelerated vesting upon retirement, Federated recognizes expense over the vesting period of the awards, regardless of the employee’s attainment of retirement age. Beginning January 1, 2006, for all newly granted awards with provisions that allow for accelerated vesting upon retirement, Federated recognizes expense over the shorter of the vesting period or the period between grant date and the date on which the employee meets the minimum age requirement for retirement. (q) Leases Federated classifies leases as operating in accordance with the provisions of lease accounting. Rent expense under noncancelable operating leases with scheduled rent increases or rent holidays is accounted for on a straight-line basis over the lease term, beginning on the date of initial possession or the effective date of the lease agreement. The amount of the excess of straight-line rent expense over scheduled payments is recorded as a deferred liability. Build-out allowances and other such lease incentives are recorded as deferred credits, and are amortized on a straight-line basis as a reduction of rent expense beginning in the period they are deemed to be earned, which generally coincides with the effective date of the lease. The current portion of unamortized deferred lease costs and build-out allowances is included in Other current liabilities and the long-term portion is included in Other long-term liabilities on the Consolidated Balance Sheets. (r) Advertising Costs Federated generally expenses the cost of all advertising and promotional activities as incurred. Certain printed matter, however, such as sales brochures, are accounted for as prepaid supplies and are included in Other current assets on the Consolidated Balance Sheets until they no longer are owned or expected to be used, at which time their costs are expensed. Federated expensed advertising costs of $2.6 million, $0.2 million and $0.1 million in 2011, 2010 and 2009, respectively. (s) Income Taxes Federated accounts for income taxes under the liability method, which requires the recognition of deferred tax assets and liabilities for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Federated recognizes a valuation allowance if, based on the weight of available evidence regarding future taxable income, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Regarding the recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return, Federated follows a two-step process prescribed by GAAP. The first step for evaluating a tax position involves first determining whether it is more likely than not that a tax position will be sustained upon examination by the appropriate taxing authorities. The second step then requires a company to measure the tax position benefit as the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. Federated classifies any interest and penalties on tax liabilities on the Consolidated Statements of Income as components of Nonoperating Income (Expenses) – Other, net and Operating Expenses – Other, respectively. (t) Earnings Per Share Basic and diluted earnings per share are calculated under the two-class method. Pursuant to the two-class method, Federated’s unvested restricted stock awards with nonforfeitable rights to dividends are considered participating securities and are included in the computation of earnings per share. (u) Accumulated Other Comprehensive Loss Accumulated other comprehensive loss, net of tax is reported in the Consolidated Balance Sheets and the Consolidated Statements of Changes in Equity and includes net of tax, the unrealized gains and losses on securities available for sale, foreign currency translation adjustments and the effective portion of the gain or loss on a derivative instrument designated and qualifying as a cash flow or net investment hedge. (v) Loss Contingencies Federated accrues for estimated costs, including legal costs related to existing lawsuits, claims and proceedings when it is probable that a loss has been incurred and the costs can be reasonably estimated. Accruals are reviewed at least quarterly and are adjusted to reflect the impact and status of settlements, rulings, advice of counsel and other information pertinent to a particular matter. Significant differences could exist between the actual cost required to investigate, litigate and/or settle a claim or the ultimate outcome of a suit and management’s estimate. These differences could have a material impact on Federated’s results of operations, financial position and/or cash flows. Recoveries of losses are recognized in the Consolidated Statements of Income when receipt is deemed probable. (w) Business Segments Business or operating segments are defined as components of an enterprise for which separate financial information is available that is regularly evaluated by the chief operating decision maker in deciding how to allocate resources and assess performance. Federated does not have multiple operating segments or business components for which discrete financial information is prepared. Federated operates in one operating segment, the investment management business, nearly all of which is conducted within the United States. Federated’s Chief Executive Officer (CEO) is Federated’s chief operating decision maker. Federated’s CEO utilizes a consolidated approach to assess performance and allocate resources.

(1) Summary of Significant Accounting Policies

(a) Nature of Operations

Federated Investors, Inc. and its subsidiaries (collectively, Federated) provide investment advisory, administrative, distribution and other services primarily to Federated mutual funds and Separate Accounts (which include separately managed accounts, institutional accounts, sub-advised funds and other managed products) in both domestic and international markets. For presentation purposes in the Consolidated Financial Statements, the Federated-sponsored mutual funds are considered to be affiliates of Federated.

The majority of Federated’s revenue is derived from investment advisory services provided to Federated mutual funds and Separate Accounts through various subsidiaries pursuant to investment advisory contracts. These subsidiaries are registered as investment advisers under the Investment Advisers Act of 1940 and with certain states.

Federated mutual funds are distributed by a wholly owned subsidiary, which is a registered broker/dealer under the Securities Exchange Act of 1934 and under applicable state laws. Federated’s investment products are primarily distributed within the wealth management and trust, broker/dealer and global institutional markets.

(b) Basis of Presentation

The Consolidated Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP). In preparing the financial statements, management is required to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying notes. Actual results may differ from those estimates, and such differences may be material to the Consolidated Financial Statements.

Certain items previously reported have been reclassified to conform with the current year’s presentation.

(d) Principles of Consolidation

The Consolidated Financial Statements include the accounts of Federated Investors, Inc. and entities or sponsored products in which Federated holds a controlling financial interest. A controlling financial interest is determined by the extent of Federated’s (1) decision-making ability through voting interests, (2) decision-making ability and rights/obligations to benefits/losses through variable interest or (3) participation in the economic risks and rewards of the entity through variable interests. To the extent Federated’s controlling financial interest in a consolidated subsidiary represents less than 100% of the subsidiary’s equity, Federated recognizes noncontrolling interests in subsidiaries. In the case of consolidated sponsored products (see Note (5)(b)), the noncontrolling interests represent equity which is redeemable or convertible for cash or other assets at the option of the equity holder. As such, these noncontrolling interests are deemed to represent temporary equity and are classified as redeemable noncontrolling interests in subsidiaries in the mezzanine section of the Consolidated Balance Sheets. All other noncontrolling interests in subsidiaries are classified as permanent equity. All significant intercompany accounts and transactions have been eliminated.

Beginning on January 1, 2010, Federated adopted the provisions of the Financial Accounting Standards Board’s (FASB) new consolidation model for variable interest entities (VIEs). As a result, Federated applies two different approaches to consider VIEs for possible consolidation. For non-investment fund entities, Federated considers a qualitative model for identifying whether its interest in a VIE is a controlling financial interest. The qualitative model considers whether Federated has: (1) the ability to direct significant activities of the VIE, and (2) the obligation to absorb losses of and/or to provide rights to receive benefits from the VIE that could potentially be significant to the VIE. Federated reevaluates the need for consolidation under this qualitative approach on an ongoing basis.

For Federated’s interests in certain investment funds that meet the definition of VIEs, Federated evaluates the extent of Federated’s participation in the economic risks and rewards of the entity based on a quantitative model to determine whether consolidation is necessary. In cases where the results of the quantitative model indicate that Federated’s interest in such an entity absorbs the majority of the variability in the entity’s net assets, Federated is deemed to be the primary beneficiary and thus consolidates the entity.

The equity method of accounting is used to account for investments in entities in which Federated’s equity investment gives it the ability to exercise significant influence over the operating and financial policies of the investee. Equity investments are carried at Federated’s share of net assets and are included in either Investments or Other long-term assets on the Consolidated Balance Sheets dependent upon management’s ability and intent to sell the investment. The proportionate share of income or loss is included in Nonoperating income (expenses) – other, net in the Consolidated Statements of Income.

(e) Business Combinations

Beginning in 2009, business combinations are accounted for under the acquisition method of accounting. Results of operations of an acquired business are included from the date of acquisition. Management estimates the fair value of the acquired assets, including identifiable intangible assets, and assumed liabilities based on their estimated fair values as of the date of acquisition. Any excess fair value of the acquired net assets over the acquisition-date fair value of the consideration transferred, including the fair value of any contingent consideration, is recorded as Goodwill on the Consolidated Balance Sheets. The fair value of contingent consideration is recorded as a liability in Other current liabilities and Other long-term liabilities on the Consolidated Balance Sheets as of the acquisition date. This liability is remeasured at fair value each period end with changes in fair value recognized in Intangible asset related expense on the Consolidated Statements of Income. For a discussion regarding the approach used to estimate the fair value of the liability, see Note (6)(a).

(f) Cash and Cash Equivalents

Cash and cash equivalents include money market accounts and deposits with banks.

(g) Investments

Federated's investments are categorized as Investments – affiliates or Investments – other on the Consolidated Balance Sheets. Investments – affiliates represent Federated’s available-for-sale investments in Federated sponsored fluctuating-value mutual funds. These investments are carried at fair value with unrealized gains or losses on securities included in Accumulated other comprehensive loss, net of tax on the Consolidated Balance Sheets. Realized gains and losses on these securities are computed on a specific-identification basis and recognized in Gain on securities, net in the Consolidated Statements of Income.

Investments – other represents trading securities held by Federated primarily as a result of consolidating certain Federated-sponsored investment companies. Federated’s trading securities at December 31, 2011 were primarily comprised of high quality short-term debt securities held by a consolidated, non-US dollar-denominated sponsored money market fund, as well as shares of an offshore master fund invested in global project and trade finance transactions and stocks of large-cap U.S. and international companies held by various other consolidated investment companies (see Note (7) for additional information). Trading securities are carried at fair value with changes in fair value recognized in Gain on securities, net in the Consolidated Statements of Income.

The fair value of Federated's investments is generally based on quoted market prices in active markets for identical instruments. If quoted market prices are not available, fair value is generally based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, or model-derived valuations in which all significant inputs and significant value drivers are observable in active markets. In the absence of observable market data inputs and/or value drivers, internally generated valuation techniques may be utilized in which one or more significant inputs or significant value drivers are unobservable in the market place. On a periodic basis, management evaluates the carrying value of investments for impairment. With respect to its investments in fluctuating-value mutual funds, management considers various criteria, including the duration and extent of a decline in fair value, the ability and intent of management to retain the investment for a period of time sufficient to allow the value to recover and the financial condition and near-term prospects of the fund and the underlying investments of the fund, to determine whether a decline in fair value is other than temporary. If, after considering these criteria, management believes that a decline is other than temporary, the carrying value of the security is written down to fair value through the Consolidated Statements of Income.

(h) Derivatives and Hedging Instruments

From time to time, Federated may consolidate an investment product that holds freestanding derivative financial instruments for trading purposes. Federated reports such derivative instruments at fair value and records the changes in fair value in Gain on securities, net on the Consolidated Statements of Income.

From time to time, Federated may also enter into and designate as accounting hedges derivative financial instruments to hedge interest-rate exposures with respect to variable-rate loan facilities (cash flow hedges) or to hedge foreign-currency exchange risk with respect to non-US dollar-denominated trading investments in consolidated investment companies (net investment hedges). To qualify for hedge accounting, the derivative must be deemed to be highly effective in offsetting the designated changes in the hedged item. For cash flow hedges and net investment hedges, the effective portions of the change in the fair value of the derivative are reported as a component of Accumulated other comprehensive loss, net of tax on the Consolidated Balance Sheets and subsequently reclassified to earnings in the period or periods during which the hedged item affects earnings. The change in fair value of the ineffective portion of the derivative, if any, is recognized immediately in earnings. If it is determined that the derivative instrument is not highly effective, hedge accounting is discontinued. If hedge accounting is discontinued because it is no longer probable that a forecasted transaction will occur, the derivative will continue to be recorded on the balance sheet at its fair value with changes in fair value included in current earnings, and the gains and losses in Accumulated other comprehensive loss, net of tax will be recognized immediately into earnings. If hedge accounting is discontinued because the hedging instrument is sold, terminated or no longer designated, the amount reported in Accumulated other comprehensive loss, net of tax up to the date of sale, termination or de-designation continues to be reported in Accumulated other comprehensive loss, net of tax until the forecasted transaction or the hedged item affects earnings. See Note (6) and Note (11) for additional information on the fair value of the hedges at December 31, 2011.

(i) Property and Equipment

Property and equipment are initially recorded at cost and are depreciated using the straight-line method over their estimated useful lives ranging from 1 to 12 years. Leasehold improvements are amortized using the straight-line method over the shorter of their estimated useful lives or their respective lease terms. As property and equipment are taken out of service, the cost and related accumulated depreciation and amortization are removed. The write-off of any material residual net book value is reflected as a loss in Operating expenses – Other in the Consolidated Statements of Income.

Management reviews the remaining useful lives and carrying values of property and equipment to determine whether events and circumstances indicate that a change in the useful life or impairment in value may have occurred. Indicators of impairment monitored by management include a decrease in the market price of the asset, an accumulation of costs significantly in excess of the amount originally expected in the acquisition or development of the asset, historical and projected cash flows associated with the asset and an expectation that the asset will be sold or otherwise disposed of significantly before the end of its previously estimated useful life. Should there be an indication of a change in the useful life or an impairment in value, Federated compares the carrying value of the asset to the probability-weighted undiscounted cash flows expected to be generated from the underlying asset over its remaining useful life to determine whether an impairment has occurred. If the carrying value of the asset exceeds the undiscounted cash flows, the asset is written down to fair value which is determined based on prices of similar assets if available or discounted cash flows. Impairment adjustments are recognized in Operating Expenses – Other in the Consolidated Statements of Income.

(j) Costs of Computer Software Developed or Obtained for Internal Use

Certain internal and external costs incurred in connection with developing or obtaining software for internal use are capitalized. These capitalized costs are included in Property and equipment, net on the Consolidated Balance Sheets and are amortized using the straight-line method over the shorter of the estimated useful life of the software or four years. These assets are subject to the impairment test used for other categories of property and equipment described in Note (1)(i).

(k) Intangible Assets

Intangible assets, consisting primarily of goodwill, customer relationship intangible assets, renewable investment advisory contracts and noncompete agreements acquired in connection with various acquisitions, are recorded at fair value determined using a discounted cash flow model as of the date of acquisition. The discounted cash flow model considers various factors to project future cash flows expected to be generated from the asset. Given the investment advisory nature of Federated’s business and of the businesses acquired over the years, these factors typically include: (1) an estimated rate of change for underlying managed assets; (2) expected revenue per managed asset; (3) incremental operating expenses; (4) useful life of the acquired asset; and (5) a discount rate. Management estimates a rate of change for underlying managed assets based on a combination of an estimated rate of market appreciation or depreciation and an estimated net redemption or sales rate. Expected revenue per managed asset, incremental operating expenses and the useful life of the acquired asset are generally based on contract terms, average market participant data and historical experience. The discount rate is estimated at the current market rate of return. After the fair value of all separately identifiable assets has been estimated, goodwill is recorded to the extent the consideration paid for the acquisition exceeds the sum of the fair values of the separately identifiable acquired assets and assumed liabilities.

Federated amortizes finite-lived identifiable intangible assets using a method that reflects the pattern in which the economic benefits of the intangible asset are expected to be consumed or otherwise used. Federated uses either the straight-line or an accelerated method of amortization after considering specific characteristics of the underlying fund shareholder base to forecast the pattern in which the economic benefits will be consumed, including fund shareholder behavior, demographics and persistency levels. The assets are amortized over their estimated useful lives, which range from 5 to 11 years. Management periodically evaluates the remaining useful lives and carrying values of the intangible assets to determine whether events and circumstances indicate that a change in the useful life or impairment in value may have occurred.

Indicators of impairment monitored by management include a decline in the level of managed assets, changes to contractual provisions underlying certain intangible assets and reductions in underlying operating cash flows. Should there be an indication of a change in the useful life or impairment in value of the finite-lived intangible assets, Federated compares the carrying value of the asset and its related useful life to the projected undiscounted cash flows expected to be generated from the underlying asset over its remaining useful life to determine whether impairment has occurred. If the carrying value of the asset exceeds the undiscounted cash flows, the asset is written down to its fair value determined using discounted cash flows. Federated writes-off the cost and accumulated amortization balances for all fully amortized intangible assets.

Federated has determined that certain acquired assets, specifically, certain renewable investment advisory contracts, have indefinite useful lives. In reaching this conclusion, management considered the legal, regulatory and contractual provisions of the investment advisory contract that enable the renewal of the contract, the level of cost and effort required in renewing the investment advisory contract, and the effects of obsolescence, demand, competition and other economic factors that could impact the funds’ projected performance and existence. The contracts generally renew annually and the value of these acquired assets assumes renewal. These indefinite-lived intangible assets are reviewed for impairment annually or whenever events or circumstances indicate that a change in the useful life or impairment in value may have occurred. Indicators of impairment monitored by management include a decline in the level of managed assets, changes to contractual provisions of the renewable investment advisory contracts and reductions in underlying operating cash flows. Federated estimates the fair value of the indefinite-lived intangible assets and compares it to the remaining book value of the assets to determine whether an impairment charge is necessary. Impairment is indicated when the carrying value of the intangible assets exceed their fair value.

Federated tests goodwill for impairment at least annually or when indicators of potential impairment exist. Goodwill is evaluated at the reporting unit level. Federated has determined that it has a single reporting unit consistent with its single operating segment based on the fact that Federated’s operations are managed as a single business: investment management. Federated does not have multiple operating segments or business components for which discrete financial information is prepared. Federated uses a two-step process to test for and measure impairment which begins with an estimation of the fair value of its reporting unit by considering Federated’s market capitalization. If Federated’s market capitalization falls to a level below its recorded book value of net assets, Federated’s goodwill would be considered for possible impairment.

(l) Deferred Sales Commissions

Federated pays upfront commissions to broker/dealers to promote the sale of certain mutual fund shares. Under various fund-related contracts, Federated is entitled to distribution and servicing fees from the mutual fund over the life of such shares. Both of these fees are calculated as a percentage of average managed assets associated with the related classes of shares. For certain share classes, Federated is also entitled to receive a contingent deferred sales charge (CDSC), which is collected from certain redeeming shareholders.

For share classes that pay both a distribution fee and CDSC, Federated generally capitalizes a portion of the upfront commissions as deferred sales commissions, dependent upon expected recoverability rates. The deferred sales commission asset is amortized over the estimated period of benefit of up to eight years. Deferred sales commission amortization expense was $7.4 million, $12.2 million and $18.5 million for 2011, 2010 and 2009, respectively, and was included in Operating expenses – Other on the Consolidated Statements of Income.

Distribution and shareholder service fees are recognized in Other service fees, net-affiliates on the Consolidated Statements of Income over the life of the mutual fund share class. CDSCs collected on these share classes are used to reduce the deferred sales commission asset. Federated reviews the carrying value of deferred sales commission assets on a periodic basis to determine whether a significant long-term decline in the equity or bond markets or other events or circumstances indicate that an impairment in value may have occurred. Should there be an indication of an impairment in value, Federated compares the carrying value of the asset to the probability-weighted undiscounted future cash flows of the underlying asset to determine whether an impairment has occurred. Management writes down the asset balance to fair value when reasonably estimable expected future cash flows are not expected to be sufficient to fully amortize the remaining deferred sales commission asset.

For share classes that do not pay both a distribution fee and CDSC, Federated expenses the cost of the upfront commission as incurred in Distribution expense in the Consolidated Statements of Income and credits Distribution expense for any CDSCs collected.

(m) Foreign Currency Translation

The balance sheets of certain wholly owned foreign subsidiaries of Federated and certain consolidated foreign-denominated investment products are translated at the current exchange rate as of the end of the accounting period and the related income or loss is translated at the average exchange rate in effect during the period. Net exchange gains and losses resulting from these translations are excluded from income and are recorded in Accumulated other comprehensive loss, net of tax on the Consolidated Balance Sheets. Foreign currency transaction gains and losses are reflected in Operating Expenses – Other in the Consolidated Statements of Income.

(n) Treasury Stock

Federated accounts for acquisitions of treasury stock at cost and reports total treasury stock held as a deduction from Federated Investors shareholders’ equity on the Consolidated Balance Sheets. At the date of subsequent reissue, the treasury stock account is reduced by the cost of such stock on a specific-identification basis. Additional paid-in capital from treasury stock transactions is increased as Federated reissues treasury stock for more than the cost of the shares. If Federated issues treasury stock for less than its cost, Additional paid-in capital from treasury stock transactions is reduced to no less than zero. Once this account is at zero, any further required reductions are recorded to Retained earnings on the Consolidated Balance Sheets.

(o) Revenue Recognition

Revenue from providing investment advisory, administrative and other services (including distribution, shareholder servicing and retirement plan recordkeeping) is recognized during the period in which the services are performed. Investment advisory, administrative and the majority of other service fees are generally calculated as a percentage of total net assets of the investment portfolios that are managed by Federated. The fair value of the investment portfolios is primarily determined using quoted market prices or independent third-party broker or dealer price quotes. In limited circumstances, a quotation or price evaluation is not readily available from a pricing source. In these cases, pricing is determined by management based on a prescribed valuation process that has been approved by the directors/trustees of the sponsored products. For the periods presented, a de minimus amount of assets under management were priced by Federated management. Federated may waive certain fees for competitive reasons such as to maintain positive or zero net yields, to meet regulatory requirements or to meet contractual requirements. Federated waived fees of $724.9 million, $653.1 million and $645.5 million for the years ended December 31, 2011, 2010 and 2009, respectively, nearly all of which was for competitive reasons. The increase in fee waivers for the year ended December 31, 2011 as compared to the same period of 2010 was primarily due to a $79.1 million increase in fee waivers to maintain positive or zero net yields. Fee waivers may continue to increase in order to maintain positive or zero net yields in addition to other competitive reasons. Fee waivers to maintain positive or zero net yields are partially offset by a related reduction to distribution expense and net income attributable to noncontrolling interests (see Note (4) for additional information on the net impact of these waivers).

Federated has contractual arrangements with third parties to provide certain fund-related services. Management considers various factors to determine whether Federated’s revenue should be recorded based on the gross amount payable by the funds or net of payments to third-party service providers. Management’s analysis is based on whether Federated is acting as the principal service provider or as an agent. The primary factors considered include: (1) whether the customer holds Federated or the service provider responsible for the fulfillment and acceptability of the services to be provided; (2) whether Federated has any practical latitude in negotiating the price to pay a third-party provider; (3) whether Federated or the customer selects the ultimate service provider; and (4) whether Federated has credit risk in the arrangement. Generally, the less the customer is directly involved with or participates in making decisions regarding the ultimate third-party service provider, the more supportive the facts are that Federated is acting as the principal in these transactions and should therefore report gross revenues. As a result of considering these factors, investment advisory fees, distribution fees and certain other service fees are recorded gross of payments made to third parties.

(p) Share-Based Compensation

Federated recognizes compensation costs based on grant-date fair value for all share-based awards granted, modified or settled after January 1, 2006, as well as for any awards that were granted prior to January 1, 2006 for which requisite service has not yet been provided.

Federated issues shares for share-based awards from treasury stock. For restricted stock awards, the fair value of the award is calculated as the difference between the closing market value of Federated’s Class B common stock on the date of grant and the purchase price paid by the employee, if any. Federated estimates the grant-date fair value of stock options using the Black-Scholes option-pricing model. Federated’s awards are generally subject to graded vesting schedules. Compensation expense is adjusted for estimated forfeitures and is recognized on a straight-line or modified straight-line basis over the requisite service period of the award. Compensation expense also includes dividends paid on forfeited awards. Forfeiture assumptions are evaluated on a quarterly basis and updated as necessary.

For awards granted prior to January 1, 2006 with provisions that allow for accelerated vesting upon retirement, Federated recognizes expense over the vesting period of the awards, regardless of the employee’s attainment of retirement age. Beginning January 1, 2006, for all newly granted awards with provisions that allow for accelerated vesting upon retirement, Federated recognizes expense over the shorter of the vesting period or the period between grant date and the date on which the employee meets the minimum age requirement for retirement.

(q) Leases

Federated classifies leases as operating in accordance with the provisions of lease accounting. Rent expense under noncancelable operating leases with scheduled rent increases or rent holidays is accounted for on a straight-line basis over the lease term, beginning on the date of initial possession or the effective date of the lease agreement. The amount of the excess of straight-line rent expense over scheduled payments is recorded as a deferred liability. Build-out allowances and other such lease incentives are recorded as deferred credits, and are amortized on a straight-line basis as a reduction of rent expense beginning in the period they are deemed to be earned, which generally coincides with the effective date of the lease. The current portion of unamortized deferred lease costs and build-out allowances is included in Other current liabilities and the long-term portion is included in Other long-term liabilities on the Consolidated Balance Sheets.

(r) Advertising Costs

Federated generally expenses the cost of all advertising and promotional activities as incurred. Certain printed matter, however, such as sales brochures, are accounted for as prepaid supplies and are included in Other current assets on the Consolidated Balance Sheets until they no longer are owned or expected to be used, at which time their costs are expensed. Federated expensed advertising costs of $2.6 million, $0.2 million and $0.1 million in 2011, 2010 and 2009, respectively.

(s) Income Taxes

Federated accounts for income taxes under the liability method, which requires the recognition of deferred tax assets and liabilities for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Federated recognizes a valuation allowance if, based on the weight of available evidence regarding future taxable income, it is more likely than not that some portion or all of the deferred tax assets will not be realized.

Regarding the recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return, Federated follows a two-step process prescribed by GAAP. The first step for evaluating a tax position involves first determining whether it is more likely than not that a tax position will be sustained upon examination by the appropriate taxing authorities. The second step then requires a company to measure the tax position benefit as the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. Federated classifies any interest and penalties on tax liabilities on the Consolidated Statements of Income as components of Nonoperating Income (Expenses) – Other, net and Operating Expenses – Other, respectively.

(t) Earnings Per Share

Basic and diluted earnings per share are calculated under the two-class method. Pursuant to the two-class method, Federated’s unvested restricted stock awards with nonforfeitable rights to dividends are considered participating securities and are included in the computation of earnings per share.

(u) Accumulated Other Comprehensive Loss

Accumulated other comprehensive loss, net of tax is reported in the Consolidated Balance Sheets and the Consolidated Statements of Changes in Equity and includes net of tax, the unrealized gains and losses on securities available for sale, foreign currency translation adjustments and the effective portion of the gain or loss on a derivative instrument designated and qualifying as a cash flow or net investment hedge.

(v) Loss Contingencies

Federated accrues for estimated costs, including legal costs related to existing lawsuits, claims and proceedings when it is probable that a loss has been incurred and the costs can be reasonably estimated. Accruals are reviewed at least quarterly and are adjusted to reflect the impact and status of settlements, rulings, advice of counsel and other information pertinent to a particular matter. Significant differences could exist between the actual cost required to investigate, litigate and/or settle a claim or the ultimate outcome of a suit and management’s estimate. These differences could have a material impact on Federated’s results of operations, financial position and/or cash flows. Recoveries of losses are recognized in the Consolidated Statements of Income when receipt is deemed probable.

(w) Business Segments

Business or operating segments are defined as components of an enterprise for which separate financial information is available that is regularly evaluated by the chief operating decision maker in deciding how to allocate resources and assess performance.

Federated does not have multiple operating segments or business components for which discrete financial information is prepared. Federated operates in one operating segment, the investment management business, nearly all of which is conducted within the United States. Federated’s Chief Executive Officer (CEO) is Federated’s chief operating decision maker. Federated’s CEO utilizes a consolidated approach to assess performance and allocate resources.
